A 50 kg bobsled slides down an ice track starting (at zero initial speed) from the top of
a(n) 173 m high hill.
The acceleration of gravity is 9.8 m/s^2.
Neglect friction and air resistance and determine the bobsled’s speed at the bottom of
the hill.
Answer in units of m/s.

Hi there!

We can use the following kinematic equation:

The initial velocity is 0 m/s, so:

vf = final velocity (? m/s)
a = acceleration due to gravity (g)
d = vertical height (m)

Plug in the givens and solve:

object 2 because all the other ones are wrong

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
